Fig. 1: Agglomeration of Ru NPs (3.3 nm) into nanowires.

A Schematic illustration of the penetration of Ru NPs into the P2VP corona of PFS29-b-P2VP230 cylindrical micelles, and transmission electron microscopy (TEM) images of typical samples obtained at different stages. B High-angle annular dark field scanning transmission electron microscopy (HAADF-STEM) and energy dispersive spectrometric (EDS) mapping images of a resulting nanowire with tightly packed Ru NPs. C XPS spectra of N 1s for nanowires sampled at different stages during the agglomeration process. D Schemes illustrate the dynamic coordination between Ru NPs and pyridine groups in the P2VP corona, which leads to a chain-like stacking of Ru NPs.
